Leaf-mine: A linear mine, frequently on lower surface at beginning; frass with closely adjoining grains.

Upper-surface, often brownish, corridor, in the end often occupying the width of a leaf segment. Older segments of the mine are much less conspicuous, lower-surface and quite shallow. Where upper- and lower-surface stretches overlap transparent patches occur, when the leaf is illuminated from behind. Frass in isolated grains, sometimes locally pearl chains. Pupation outside the mine (Bladmineerders van Europa).

Larva: The larva is described by de Meijere (1926) and Hering (1967: 25). The posterior spiracles have 13-17 bulbs. The posterior spiracles are illustrated in Bladmineerders van Europa.

Puparium: Black; posterior spiracles each with 15 bulbs.
